Waveguide Mode Transition

SWT-19188-SB is a WR-19 to 0.188" diameter circular waveguide mode transition. The mode transition is manufactured by either EDM machining or electro-forming techniques to ensure high accuracy and a quality surface finish. The transition only induces a fraction of a dB insertion loss and offers a return loss of 32 or better. The nominal operating frequency is 43 to 50 GHz. The dominate mode frequency range can be extended to cover 40 to 60 GHz if the higher order waveguide mode is not excited.
